tion serially numbered 310,739, filed by Hubert Hopkins in the UnitedStates Patent Oflice on or about April 9, 1906. \Vhile the presentimprovements are designed to be applied to the machine in said patentsand application, it will be understood that by obvious alterations andchanges these improvements could be applied to other types ofcalculating machines, and I do not wish to be understood as limiting myinvention to the particular machine shown. In the machine shown in saidpatents and application there are three groups of accumulating wheels119 laterally movable with respect to the actuating racks 100, and agroup of accumulating wheels 268, also laterally movable in a step bystep operation, with respect to the racks 100, which step by stepmovement is incident to the operations of multiplication. The machineshown in said patents is of the traveling carriage type in which rows ofsetting-up pins 63 in said carriage are successively brought undercontrol of the ten keys representing zero and the nine digits, and whenthe pins are set up to represent the number in the carriage saidcarriage is lifted upon the initial forward stroke of the handle so asto position stop pins 93 in a stationary field of stops. The racks moveforwardly while out of engagement with the Wheels 119 or 268, and whenthe handle reaches its forward limit of movement either set of wheels119 or 268 is engaged with the racks and the number represented by saidracks may be introduced into either set of accumulating wheels. Thenormal operation of the machine is to introduce and accumulate numbersinto a group of wheels 11.9 without operating any of the result keys;but to introduce a number into the wheels 268 in additive operations theD or decimal key is depressed to move the cams 82 109 to their thirdposition so as to place them in control of said wheels 268 and out ofcontrol of the wheels 119. Normally, when no result key is depressed,the cams 82109 are in control of the wheels 119 and act to engage saidwheels with the racks afterithe racks have reached their forward limitof movement, said wheels remaining in engagement with the racks duringthe return movement of the latter, the wheels being disengaged from theracks just before the handle reaches its home position.

To obtain a total from the wheels 119 the 1" key is depressed, beforethe handle is pulled. The T key moves the cams 82l09 to their second orneutral position and also engage-s the wheels 1 19 with the racks sothat said wheels will be reversely rotated by the forward movement ofthe racks and until. their tripping projections engage the zero stops ofthe carrying mechanism whereby the total formerly represented by saidwheels will be transferred to the racks, which racks will now be inposition to print the total. If the total key is permitted to rise whenthe handle is forward wheels 119 will stand clear or at zero; or if thetotal key is held depressed the wheels 119 will be rotated by thebackward movement of the racks and the total re-introduced thereinto.

To obtainia total of numbers accumulated in the wheels 2618 or to printa product represented in said wheels as a result of multiplyingoperations the P key is depressed, but this P key does not in thestructure disclosed in said patents, move the cams 82-109 to theirsecond or neutral position. The P key engages the wheels 5268 with theracks so that when the handle is moved forward the racks will reverselyrotate the wheels 268 until said wheels represent zero, whereupon thenumber formerly represent ed in said wheels will be transferred to theracks and a record may now be made of such total or product. If the Pkey is released when the handle is forward the wheel 268 stands clear,or if the P key is held depressed while the racks and handle are movingbackward the number will be re-introduced therein. It will thus be seenthat in the machine disclosed in said patents a product or series ofnumbers introduced into the wheels 268 and therein accumulated will,when said product or total is obtained from said wheels, be transferredto and introduced in a set of wheels 119. The wheels 968 are principallyused to accumulate units and tenspartial products in the operation ofmultiplication and in making out invoices where, for instance,' a numberof yards is multiplied by the price per'yard, these extensions, as theyare called, are accumulated in a set of wheels 119 so that the total orfooting of said extensions may be printed at the bottom of the columnthereof. Ordinarily, in thus carrying out extensions, it is notdesirable to hold the' P key depressed so as to re-introduce the productor total into the wheels 268 because by so doing it would be accumulatedwith the next succeeded product, and when the sum of these two totals orproducts was obtained said sum would be accumulated in the wheels 119and because of such repeated transfer of the ents, it is alsopractically impossible to operate the T key before the handle is pulledso as to reversely rotate the wheels 11%) the same distance they will berotated when the racks move rearwardly to introduce a product from thewheels 268, thereinto, for two reasons,first, any wheel 119 standing atzero or to represent any digit smaller than the digit of correspondingdenominational order in the wheels 268, would prevent the rack in thatdenomination from moving forward the proper distance; and second, thedepression of the T key would move the cams 82-109 to their secondposition, whereas when the P key is depressed it is intended that saidcams shall remain in their first or normal position.

In the machine shown in the accompanying d awings, the T key and itsconnections operates substantially the same as the T key of theaforesaid patents and application. The D key, when fully de pressed,also operates substantially the same, so far as its function of throwingout the escapemeut mechanism of the carriage g 57 so'as to place adecimal rack bar under control of the key board, is concerned, and saidD kev after a number has been set up on the key board will, when do p1cssed,

shift the can s 82-109 to their third position so as to introduce saidnumber into the rear totalizer wheels 268. This operation is alsoslmilar to that described 1n the patents and application referred to.Means are in the Wheels 268. No latch is provided to 5-..

the racks reach the forward limi s of their movement.

The E or extension key. in the patents and application referred to, didnot shift the cams 82-109 to their neutral position but permitted saidcams to emain in their first position with the result that when a numberwas set up on the key board, the l l key depressed and the machineoperated. said number would be represented by the pendants and alsointroduced into a group of wheels 119. In the present case, when the Ekey is depressed, the cams are shifted to their neutral positi n andconse uently the number set up on the key board can not be introducedinto the group of wheels 119 but is represented by the pendants 235. TheE key in the patents and application a oresaid. used to obtain theproduct or total accumulated in the wheels 268, when depressed, wouldnot shift the cams 82 d and consequently the number represented on saidwheels will be introduced into the group of totalizer wheels 119. In thepres ent instance, there are two keys for controlling the wheels 268.Vith respect to obtaining the product or total therefrom, one of thesedesignated as the first product key performing the function of the P keyreferred to with the exception that, when operated, it does not effectreioration of the pendants, but leaves said pendants set up to representa multiplicand for another or succeeding operations of multiplication;or the number represented by the pendants may be used as a subtrahendand be subtracted from the number represented by the wheels 268. lVhenthe first product key is operated, the inultiplicand will be l ft in thependants 235, the wheels 268 cleared or returned to zero and the numberrepresented in the wheels 268 transferred to a group of wheels 119.

The second product key, designated as the final product key will, whenoperated, effect the restoration of pendants 1235 and clear the wheels368 when the number therein represented is transferred to a group ofwheels 119. There are three additional keys shown in the drawings whichare not disclosed in the patents and application referred to. These keysare located at the left-hand side of the machine and for want of spacein the key board are not connected to bell crank levers, as are theother keys. but are in the form of push rods.

The S or subtraction key when a number is represented in the pendants235 will, when pressed rearwardly and the machine operated, subtract thenumber represented. in the pendants 235 from the number repre sented inthe wheels 268, the wheels 268 containing the correct remainder at theend of such subtracting operation.

The key marked A will. when pressed rearwardly. place the cams 82--10l)under control of the l l or extension key whereby the number set up onthe key board may be represented in the pendants 23.3 and not beintroduced into a group of wheels 11%: or. if said A key is pulledforward, the number introduced into the pendants will be also introducedinto a group of wheels 119.

The key marked B when pushed. rear wardly will enable the nunilmrrepresented in the wheels 208 to be printed without being introducedinto a group of wheels 11). the wheels 268 standing clear at the end ofthe'operation unless the first or final prod uct key is held down whilethe racks are moving rearwardly. When the B key is pulled forward anumber represented in the wheels 268 will be transferred to a group ofwheels 119 when the first or final product key 'is depressed, saidWheels 263 standing clear at the end of such operation or having thenumber rc-introduced thereinto by holding the first or final product keydepressed during the backward move ment of the racks.

Many of the parts shown in the accompanying drawings are substantiallythe same in construction and function as corresponding parts shown inthe patents and applica tion aforesaid and, Wherever practicable, I haveemployed the same reference numerals to refer to such correspondingparts.

81 indicates a shaft on which the cams 82-109 are slidingly mounted,said cams being connected together by a hub portion, as shown in Fig. 4,and between the cams is arranged the head of a lever .181. Lever 181 isin the form of a bell crank pivoted to a bracket secured to the baseplate of the machine (see Fig. 2), its horizontal member being notchedin its lower edge shown in Figs. 7 and 9. these note. es being locatedover the rear ends of certain bell crank levers operat d by the resultkeys now to be described.

The T or total. key Fig. 12) is connected by a rod 170 to a bell crank172, the forwardly extending member of which cooperates with a pin orlink. 185, the upper end of which link is connected to a tappet 84whereby when the T key is depressed, .link 185 raises the rear end oftappet 8-1 out of the path of movement of pin 83 on cam R2. Thus the armcarrying the tappct 84. is not operated and the laterally movablecarriage 5'? containing the pins 3 is not raised to position any of thestops 93. The upper end of the bell crank lever 172 is coir nected by alink 17 5 to a T'siiaped lever 173 whose forwardly extending projectionlies over the pin on the lower end of bar .3, which bar is connectetd atits upper end M) a hell crank lever 11.4 operating a cam faced bar 115tending to more the same for wardly when the T key is depressed so as tolower the frame 49 pivoted on shaft 50 in which shaft 19 carrying theWheels 119 is slidingly mounted.

The rearward extension of the T-shaped lever 17 3 lies under thehorizontal member 180 of the bell crank but not in line with any notchon the lower edge thereof. as shown in Fig U. whereby when the T key is:3 pressed. the bell crank Him-191 is shifted 1o its central or neutralposition locating the ram'SE between the pins 111. and 274, whereby whenthis cam is rocked, neither the rod 113 will draw the forward totalizerwheels 11$. into mesh with the racks at the beginning of the rearwardexcursion of the racks, nor the rod 272 draw the rearward totalizerwheels 268 into mesh with the racks as would ordinarily be done if thecam occupied its first or third position. The operation of the tappets112 on the rod 113, and 273 on the rod 272, which tappets carry the pins111 and 27 1, is fully described in the patents beforementioned andtherefore such description need not be repeated here. Likewise, when theT key is depressed, cam 109 which normally cooperates with pin 141 ontappet 140 carried by rod 138, will be shifted out of alinement withsaid pin 141 and not operate the rod 138. Rod 138 is connected to thecarrying mechanism identified with the wheels 119 and will restore orreset said carrying mecha; nism when the cam 109 is in the positionshown in Fig. 4. When shifted to its third position as by the depressionof the D key, earn 109 will be moved out of control of bar 138 andplaced in control of bar 138*, which latter cooperates with the carryingmechanism for the wheels 268, all of which is described in thebeforementioned' patents.

From the above description, it will be observed that when the T key isdepressed, the rod 113 is drawn downward so as to engage the wheels 119with the racks before said racks start forwardly and the cams 82 109 areshifted to their central or neutral position so that they will notmechanically operate to engage or disengage the front or rear totalizerswith the racks nor will they operate to reset the carrying mechanism foreither the front or rear totalizers.

The D key and its connections are shown in Figs. 16, 17, and 18. The rod340 which is operated by the D key is connected to a link 341 in turnconnected to a bell crank lever 34- 1, whose rearwardly extending memberis provided with a head (see Fig. 17) which engages a slot in the forwa.1 end of the lever 315, the rear end of said lever having a cam facedlateral projection 316 which engages a pin on shaft 220 so as to movesaid shaft laterally whenever the D key is depressed. Shaft 220 carriesa plate 219 (see Fig. 5) to which is secured an overhanging plate 219*,the latter extending over and engaging the rearwardly extending curvedfingers at the lower ends of the supplemental bars 102. These bars areslotted at their lower ends where they engage the shaft 106 so that saidbars may be raised when the plate 219 is rocked upwardly. lVhen thesupplemental bars are raised, (see Fig. 11) the slots in their upperends receive pins or lateral projections 217 on the main levers, whichlatter are connected to the racks and partake of the movement thereof.Each supplemental bar 102 has a link 231 pivotally connected thereto(see Fig. 1 which link is provided with a tooth 232 coiiperating with anotched upper edge of a segmental plate 233, there being one such platefor each supplemental bar. Link 231 has lateral. projections 234 at itsrear edge for engaging the pendant said pendant being slidingly mountedupon the rearwardly projecting track extension 236 arranged upon thestepped stop bar 239. Hence when the plate 219 is raised all ofsupplemental bars 102 are locked to the main levers 102 and as the racksmove forward against the positioned stop pins 93, the pendants 235 willbe correspondingly positioned. Vhen the plate 219 is lowered, the teeth232 will engage the segmental plates 233 and lock the pendants inposition. \Vhen the D key is depressed to move the shaft 220 laterally,plate 219 is correspondingly moved, but this movement is idle andmeaningless. However, the rock arm 221 mounted on shaft 220 is movedlaterally for the purpose of locating the pin 221 carried by the forwardend thereof out of alinemeut with the bell crank lever 310 operated bythe final product key. this manner, the D key may be depressed half wayand the final product key pressed for the purpose of restoring thependants without clearing any of the totaliaer wheels. key in itshalf-way depressed position. shown in Fig. 16, where it will be seenthat the spring pressed plunger 600 is arranged alongside of the D key,the stem of which plunger carries a cone-shaped head 01, whichcooperates with a pin 602, said pin being held against the cone-shapedhead by means of a spring. \Vhen the D key and the plunger 600 aresimultaneously depressed the horizontally movable pin is moved under theshoulder 603 on the D key and consequently the simultaneous depressionof the D key to be arrested in its half-way position; whereas, if theplunger is not depressed and the D key alone is operated, the pin 602will not be arrested under the shoulder of the D key and hence said Dkey can be fully depressed. The half-way depression of the D key placesthe cams 82-409 in their neutral position and also moves the shaft 220so that its arm 221 will not be operated when the final product key isdepressed. The I) key is also connected by a rod 349 to the,escapementmechanism which controls the laterally movable carria e.

The depression of the key (see Fig. 13) will operate rod 325 connectedat its rear end to lever 326, in turn connected by link 328 to a bellcrank lever 329. The rearwardly extending member 331 of this bell cranklever 329 lies under a pin 221 on a rock arm 221 so that whenever the Ekey is depressed, shaft 220 will be.rocked and the supplemental levers102* raised into Means for holding the l) 1- engagement with the pins217 on the main le ers 102, thus connecting the pendants with the racksso that the pendants will be positioned according to the position of theracks and the number represented by the racks in their forward positionwill also be represented by the pendants when the E key is released todisengage the pendants from the racks when the handle reaches theforward limit of its movement. The extension 331 of this E key normallylies under a notch in a horizontal member of the cam shifting bell crank180 and. when the A key is pulled forward its cone a will permit theblocking plate a to be moved outwardly so as to open the notch 180 Fig.6), the operation of the E key will not shift the cams 82109 andconsequently, any number set upon the key board when the E key isdepressed and the handle pulled, will not only be set up or representedby the pendants 235, but will be registered in one of the groups ofwheels 119, because cams 82109 are not shifted If it is desired to setup a number from the key board in the pendants 235 and not introducethat number into any group of wheels 119, the key A is pressedrearwardly whereby its cone L will move the blocking plate a to theposition shown in Fig. 7 whereby when a number is set upon the key boardand the E key is depressed, the bell crank 180181 will be rocked toshift the cams 82109 to their neutral position so that, when the handleis pulled, the number set upon the key board and .introduced into thependants 23. will not be introduced into a group of wheels 119.

The P or product key and its connections are illustrated in Fig. 14 andas stated above in the patent referred to, the function of this key waswhen depressed to cause the wheels 268 to be meshed with the racks uponthe forward movement of the handle so as to yield a total or productfrom said Wheels and at the same time, introduce said total or productinto a group of wheels 119.

The B key shown in Fi 5 is connected by a rod to a cone Z), W ich cone bcooperates with a blocking plate 6 (see Fig. 8).

The P key shown in Fig. 14 is connected by a rod 302 to a bell crank 303whose forward extension when the P key is depressed, depresses the rod185 and raises the tappets 84 out of the path of the pin 83 on cam '82for purposes heretofore described. Bell crank 303 is connected by link305 to a T-shaped lever 307 whose forwardly extending portion 308- engaes the pin 309 and, depresses the 2.72, w ercby the frame 270 carryingthe rear totalize'r wheels 268 is depressed and a set of wheels enga edwith the racks whenever the P or rst product key is depressed. Upon thedepression of this P key, if the key B is pulled forward so that thebocking plate Z1 uncovers the notch 180 in the horizontal member 180 ofthe cam shifting lever, as shown in Fig. 8, then the total or productcontained in the wheels 268 will be transferred to and registered in agroup of wheels 119. If, however, the key B is pushed rearwardly beforethe P key is o eratedso as to close the notch above the lever 307operated by the P key, as shown in Fig. 9, the depression of the P keywill rock the cam shifting lever moving the cams 32-109 to their centralor neutral WVhen the notch is thus opened (see wheels 268 will beyielded but not introposition in which a number contained in the ducedinto a group of wheels 119., The wheels 268 will stand clear at the endof the operation if the P key is permitted to rise when the handlereaches the forward limit of its movement; or if the P key is helddepressed, the number will be retained in the wheels 268. The operationof the P key in the present construction does not shift any of themoving parts into control of the restorin bar 315 (see Fig. Zl whichcooperates with the extensions 316 of the supplemental bars 102 torestore the pendants 235 to zero position. In the aforeaid patents,Whenever the P key is depressed, the restoring bar 315 will be. operatedand the pendants restored. In my present construction, the operation ofthe P key will not place the. restoring bar 315 under control of any ofthe moving parts of the machine, and consequently, the

pendants will be left setup to represent a multiplicand or subtrahend,as the case may or final product key are separate and distinct fromthose operated by the P key and consist of a rod 325 connected to a bellcrank 303. in turn connected by link 305* to a T-shaped lever 307 whoseforward extens on 308 engages the pin 309 todraw down the bar 272.forthe purpose. and in the manner described with reference to correspondingparts operated by the P or first product key. A rearward extension 310operated by the F. P. key extends under pin 221 on a rock shaft 221 (seeFig. 3) so as to rock shaft 220 and raise supplemental levers 102 intoengagement with the pin 217. At the same time, the rearward extension310 engages a horizontal member of a bell crank 311, Figs. 2 and 4) andshifts the bell crank 317-314, the latter member of which carries therestoring bar 315, the former member being placed in the ath of the pin31S carried by the cam 9 and the shaft 81. In this manner, when thefinal product key is depressed, it operates similar to the P key in thepatent before mentioned in that it raises the supplemental levers 102 sothat the teeth 232 are raised out of engagement with the segments 233,but the supplemental levers 102 are not raised sufiiciently high toengage the pins 217 on the main levers; the wheels 268 are drawn downinto mesh with the racks; and the restoring bar 315 placed under controlof amoving part of the machine. \Vhen the handle is pulled, the total orproduct will be yielded from the Wheels 268 and the pendants 235restored to zero position. If it is desired to introduce this finalproduct key into a group of wheels 11.), the B key is pulled forward. sothat the blocking plate 7. will be received in the notch 180" and willoecup y the position shown in Fig. 8, in which position the rearwardextension 310 will not operate the cam shifting bell crank; but if it isdesired to take a total or product direct from the wheels restore thependants to Zero and not introduce said total or product into a group ofwheels 268, the B key is pushed rearwardly, blocking the recess 130 overme extension 310 as shown in Fig. 9, so that when the F. P. key isdepressed, cams 82-109 will be shifted to their central or neutralposition.

In Fig. 15, I have shown the S or subtraction key and its connections,the same comprising a rod 500 connected to a bar. having a beveledlocated under the extension 180 of the cam shifting lever. This bar isconnected to a lever 501 pivoted to the base plate of the machine, theopposite end of which is connected by rod 502 to a lever 503 whose upperend coiiperates with a lug 504 on the. subtraction plate whichcooperates with the pendants-185 in performing operations ofsubtraction. The operation of subtraction mechanism is disclosed inUnited States Letters Patent granted on an application filed by HubertHopkins, said patent being Number 1,118,489, and dated November 3 1914,and do not claim the same hei err-apt in combination with the E key andits connections whereby a number represented by the pendants may be usedeither as a multiplicand. the partial products being accumulated in thewheels or as a subtrahend, the complement of which is added to theminuend standing in wheels 268 and 1 automatically introduced into theunits column when the subtraction the multiplier keys and pulling thehandle as explained in the beforementioned patents; or a remainder, bysubtracting the number represented by the pendants from the minuendstanding in the Wheels 268 by the method of complementary addition asset forth in Mr. Hopkins pending application just before referred to.The pendants 235 constitute what may be designated as setting up devicesin which a number, multiplicsnd or subtrahend is represented or set upby the position of said pendants,

What I claim is:

1. In a calculating machine, the combina-' tion of variably positionableparts 235 which constitute setting up devices, a totalizer, a key board,means under cont ol of the operator for setting up a number in the saiddevices and simultaneously introducing said number into said totalizer,and a key and its connections whereby a number may be set up in saiddevices independently of any operation of said totalizer.

In a calculating machine, the combination of variably positionable parts235 which constitute setting up devices, a totalizcr, means forpositioning said parts to represent a number at the time that saidnumber is introduced into said totalizer, and means under the control ofthe operator for returning said parts to zero position independently ofany operation of said totalizer.

3. In a calculating machine, the combination of variably positionableparts which constitute setting up devices, means for positioning saidparts to represent a number, two totalizers, a key and its connectionswhereby the number introduced into one of said totalizers will besimultaneously :.;presented in said setting up devices, and another keyand its connections whereby said setting up devices are placed incontrol of the other totalizer, and another key and its connectionswhereby the number represented in said last mentioned totalizer may becleared therefrom independently of any operation of said first mentionedtotalizer and setting up devices.

4. In a calculating machine, the combination of variably positionableparts constituting setting up devices for representing a number in thenature of a multiplicand or subtrahend, a totalizer, and a plurality ofkeys for placing said setting up devices in control of said totalizerfor difi'erent arith- 1 metical computations, such as multiplication andsubtraction.

5.
